Emerging mixxx failed. I have tried with gcc i686-pc-linux-gnu-3.3.4 and i686-pc-linux-gnu-3.4.3.

I'm not sure about it as I don't have way to install it (masked under amd64) but probably the problem resides in QT. Have you built qt with or without opengl support? Have you tried to run revdep-rebuild?
I have recompiled QT without the opengl USE flag (it was compiled with opengl). I also ran revdep-rebuild, no packages needed to be recompiled. I then emerged mixxx again but got the same error. I also tried to compile it with the jack USE flag but that also didn't work. Any other ideas?
Yeah, you need qt build with opengl enabled, and you need to use the same compiler for qt and mixxx
Hmm, I have recompiled QT and all kde stuff that uses the opengl USE flag. And now Mixxx compiles without errors. Solved :)
marking as fixed wrt to comment #5
